  6. Wavetable sequencing and the waveform parameter

    in MIDIbox SID

    Posted · Edited by jaytee

    Ok, that the documentation was wrong clears a lot of stuff up. Logically, I knew it had to be a 7-bit parameter, but the parameter list was throwing me for a loop.

     

    I don't know the digital conversions by heart, but I'm familiar enough with the process. I wrote a patching interface in Lemur for my MKS-7, which handles several sysex parameters in the same way.

     

    I still can't figure out what I was doing wrong with the tutorial though. Even if the values I was using were incorrect (ie relative instead of absolute), I don't know why the sound would have been inconsistent upon each keypress. I'll have to go back and try it again to see if I can replicate my results. If so, I'll post a recording and take note of my settings.

  7. Wavetable sequencing and the waveform parameter

    I was hoping that someone a little more well-versed in wavetable sequencing could help me out. I'm pretty comfortable with 90% of the features in my sammichSID, and it's my go-to synth when it comes to complex sound design (the mod matrix, the crazy envelopes, six oscillators and two filters to play with; the only thing I own that's more powerful is my K2000, and it's not nearly as fun) but I've stayed away from the wavetable sequencer until now.

     

    However, I find myself wanting to roll my own drum sounds (and perhaps experiment with the other sound design possibilities that the WTs open up) and that is gonna require me to learn. For the most part, it actually all feels pretty straightforward. I understand the concept, I've played with parameter sequencing on other synths before, and I'm used to the limited interface of the sammichSID by now. 

     

    The one thing I can't wrap my head around, however, is the waveform parameter. In the parameter chart here, the "description" column shows the parameter as a 7-bit number (0-127), with each bit controlling a different flag. However, the "range" column claims that this parameter only goes from 0-15 (4-bit number). Then there's the "reset" column, which in other parameters seems to be the "off" or "neutral" position (typically the highest, lowest or median value within the possible range), but here is mysteriously listed as "4." Can anyone elaborate on how this parameter works?

     

    FWIW, I tried to figure it out based on both trial and error as well as following the v1 WT tutorial. Trial and error got some interesting and reproducible results, but I still couldn't figure out what values corresponded to which waveforms. Following the tutorial (just the first section on creating a kick drum), I got some truly strange and inconsistent results, with each consecutive keypress slowly morphing from a tonal sound to noise before going silent; sometimes I could get this behavior to reset, while other times the sammichSID would just stay silent until switching patches. Really weird stuff.

     

    the only other thing I'm having a little trouble with is the relative values vs the absolute values. Do they function basically the same, and are just both present to accommodate different parameters that make more sense with one than the other? Or is there something more complex happening that I don't get? I only realized that both were present about halfway through my experimentation, so it's fully possible that some of my difficulties were due to setting the wrong type of value (ie setting +04 instead 04). Does that sound right?

     

    thanks for the help.

    No disrespect is intended, and my response was not necessarily directed solely at you but rather at all the recent high-priced sammich sales. I thought that was clear, but perhaps not.

     

    All the same, the license agreement clearly states that resale a should not be for more money than what parts and assembly cost. $500 is nearly double what the kits originally cost. If you think your troubleshooting and train ticket costs count as assembly (and totaled ~$250), go for it. I'm just a dude on the Internet, it shouldn't really matter if I think it's rude to ask such a price.

    $500 for a sammichSID with admittedly questionable internals? We do all remember that part of the MIDIbox license is not reselling these units for profit, right? I get that if someone else is willing to pay it, there's not much any of us can do to stop the sale, but to advertise it here, so blatantly flouting the license agreement, seems rude at the very least.

     

    FWIW, I already own a sammichSID, and if I buy another, it'll be one of the upcoming kits. So this isn't me trying to get a better price; if anything, it's nice to know that my gear is going up in value. But seriously people, just a little respect for the people that made this gear possible?

  11. MIDI note out from Sequencer?

    in MIDIbox SID

    If the only reason you want this is to get that first note-on to wake up your module (ie you don't want to actually sequence with the sequencer), you could modify the sammichSID code to arbitrarily output a midi note at some desirable point in operation. I recall at one point, I had my sammichSID setup to use the out as a soft thru (or maybe merge?), so it wouldn't be impossible to figure something out that will wake your module, even if the sequencers won't work.

    Can someone explain to me what the three options in the lower right of the OSC panel are for? Where you choose your SID, mono/stereo, and your filter caps? I figured it would be like a quick change to calibrate all your filter settings at once, but it seems to have zero effect that I can see. I checked the manual for these options in the menus of the synth itself and didn't see anything analogous either. On the other hand, they make my patch bay blink, so they're obviously sending *something*.

     

    Not a big deal, just curious.
